The both of you have interesting problems. To tackle BlackHeat's, we need his system back up and running. From previous posts and threads, we are banking on a video card problem, but addressing any cooling problems in the meantime is a good idea any ways.

RJARR..... the way you put hardcoding and low shut down temp is interesting. I'd relate this to a report rather than say it's hard coded.
All I can tell you from any experience I've had with probably a good 10 or 12 FX processors, I've never seen what you'd call a low temp shut down. I'm so familiar with Asus over any other board, it's not funny. I could write a very long winded post about Asus motherboards and their functions in great detail, but it won't solve issues in most cases.
If I where you, I'd test the PSU. Firstm a multimeter on the 12v rails. Then test the 5v rails. You get a dip exceeding more than say 5-10%, that PSU is no good. Another way to test is by trying a spare PSU you might have laying around that is in good standing.
Speaking of power supply, multiple rail PSU's need to be balanced so to speak. Let's say you have 3 12v rails instead of one. If you load One of those three rails too much more than the other two, it may cause issues like random shut downs. I've seen this many times.
A PSU overheat would cause a shut down. I've actually upgraded the fan on my 1000w Antec Continuous Power Series PSU because it would run hot while using LN2 and pushing 2.0v on the CPU. The wires would actually even get warm. The upgrade also helped with running high wattage TECs (which is one of my things I like to do) and that also puts a very heavy load on the PSU. And I mean big time. You could try and reconfigure the peripherals attached to your PSU and see if that helps any.
After reviewing your SIG really quick, this is what I see.
+3.3V@30A; +5V@28A; +12V1@18A; +12V2@18A;

500W = max power output. Efficiency > 85% = 85% typical load capacity. This PSU may just not be big enough.
GTX 660ti =
Maximum GPU Tempurature (in C) 97 C
Maximum Graphics Card Power (W) 150 W
Minimum System Power Requirement (W) 450 W
The FX-8350 uses roughly 210W at load 4ghz. At 4.8ghz around 385W
The 660ti (stock load) and FX-8350 (4ghz load) together at load are using 360W just for these two pieces of hardware. We are not counting the HDDs, motherboard DVD rom, fans and so on.
85% of 500 is 425W. you'd think that 500W is plenty, but in this case, I don't think it is. You have 65W of head room if you where to load CPU and Video card.
So after crunching some numbers there, You may want to slim the power usage (even though we haven't gone into amp usage yet) and see if you can cut some power here and there,
or go with a larger power supply.
Running a FX processor with 8 cores is no joke. Always look for over kill with 2 things concerning a FX processor. 1 cooling and 2 PSU.
650w - 850w closer to 850W would be ideal. Leaves room for extra HW, SLI or crossfire and overclocking.
How important is a PSU for overclocking? Well VERY important. Lemme give an example. While running LN2, I gained 200mhz upgrading the psu from 850w to 1000w during a max clock LN2 run. That would be a jump from 7450mhz to 7685mhz with the exact same set up nothing changed except the PSU.
Long winded post. But I hope you take the time to read it all. ^^
